A drop sensor detects a drop of a device. When the drop of the device is detected, a sub CPU allows a counter to count a drop time. When the device drops for a predetermined time or more, the sub CPU controls a regulator so that the regulator forcibly disconnects an electric power to be supplied to a hard disc, and writes a drop occurrence flag into a nonvolatile memory. When the power supply is again turned on, a main CPU allows a display section to display information indicating that the power supply is disconnected due to the drop of the device.
Legal claims defining the scope of protection, as filed with the USPTO.
1. A recording/reproducing device that records or reproduces information, comprising: a recording/reproducing section that records or reproduces the information; a file creating section that creates a file with a predetermined format where an actual data file containing video data is pared with a management information file as management information of the actual data file; a file recording management section that is provided with a first folder for storing the file with the predetermined format and a second folder for storing another file as folders to be used for recording the information in the recording/reproducing section, and manages files to store the file with the predetermined format in the first folder when the file with predetermined format is recorded in the recording/reproducing section; a power supply that supplies an electric power to the recording/reproducing section, the file creating section and the file recording management section so as to bring the recording/reproducing device into an operating state; and an operating section that gives instructions for turning on and disconnecting the power supply, wherein in a case where the power supply is turned on by the operating section after disconnecting the power supply so that the recording/reproducing device is brought into the operating state, when the management information file to be pared with the actual data file created before disconnecting the electric power is not normally created, the file recording management section manages the recording of the file so that the actual data file is stored in the second folder.
2. The recording/reproducing device according to claim 1 , wherein when the management information file to be pared with the actual data file created before disconnecting the electric power is not normally created, the file recording management section manages the recording of the file so that the actual data file is stored in the second folder, by an instruction for restoring the file from a user.
3. The recording/reproducing device according to claim 1 , wherein the actual data file is an MOD file based on an SD-Video specifications, and the management information file is an MOI file based on the SD-Video specifications.
